How dangerous are microplastics? | DW Documentary

Summary

This video follows the development of an innovative technology designed to remove microplastics from wastewater. A special 'hydrocyclone' machine uses centrifugal forces to separate plastic particles, with promising results from initial tests. The project is seen as a positive investment for the future of Röthenbach, with local support and minimal cost increases for residents. The inventor, a DJ-turned-professor, is dedicated to finding practical solutions to plastic contamination. Despite the long road ahead, the team at Bayreuth University remains committed to their mission of making microplastics history, working tirelessly to minimize environmental harm.

Q & A

What is the main purpose of the 'hydrocyclone' machine described in the video?

The main purpose of the 'hydrocyclone' machine is to filter microplastics from wastewater by using centrifugal forces that push the plastic particles to the inside, where they can be separated.

How does the 'hydrocyclone' machine work to separate microplastics?

The machine subjects the wastewater to massive centrifugal forces during the cleaning process. This action pushes the plastic particles to the center, allowing them to be separated from the water.

What were the results of the initial testing of the machine at the treatment plant?

Initial testing at the treatment plant showed promising results, with the machine successfully removing the majority of microplastics from the wastewater.

How does the mayor of Röthenbach view the new technology?

The mayor of Röthenbach views the hydrocyclone machine as an important investment in the future of the community, emphasizing its potential positive impact on the environment.

What is the cost of implementing the new filter for residents?

The new filter will only add a couple of euros to the annual wastewater bill, which is considered affordable for the residents.

What is the broader objective behind the research and development of the hydrocyclone machine?

The broader objective is to find solutions to the microplastic problem, rather than simply highlighting the issue. The researchers are committed to providing actionable answers and minimizing contamination sources.

What does the inventor of the filter feel about realizing the vision of the project?

The inventor describes the experience of realizing the vision as feeling like a pioneer or someone 'tilting-at-windmills,' acknowledging that solving the plastic problem will take a long time.

Why does the inventor believe the plastic problem will remain for centuries?

The inventor believes the plastic problem will persist for centuries or even millennia because plastic in the environment does not break down quickly, making it a long-term issue.

What is the ongoing goal of the researchers at Bayreuth University?

The ongoing goal of the researchers at Bayreuth University is to continue finding solutions to the plastic contamination problem, with no end to their experiments in sight.

How does the DJ-turned-professor contribute to the project?

The DJ-turned-professor contributes by leading the research efforts with a passion to make the world a 'groovier' place, using innovation to address the serious issue of microplastics.
